Russia-based EuroChem has started production of phosphate ore at the Kok-Jon phosphate rock deposit in the Jambyl region of Kazakhstan.
The company has produced around 20,000t of phosphate ore from the site so far and shipped it to a nearby storage facility.
EuroChem is expecting to produce more than 150,000t of phosphate ore by the end of this year.
Under the first phase of the project, the company aims to increase its production capacity to 650,000t a year in 2016 and ultimately reach its target of 1.5 million tonnes.
The company has invested $75m in the project to date and plans to construct a fertiliser complex in the area.
EuroChem mining director Clark Bailey said the company is pleased with the early results of the Kazakhstan project and the new mine at the Kok-Jon phosphate rock deposit.
"The first product from the mining operations is being realised just a few months after we started developing the deposit," Bailey said.
"This is a testament to the professional team and dedicated leadership that we have assigned to these operations. The project continues on schedule with the planned ramp-up of the production capacity."
The increased production will also create employment opportunities for the locals and improve social infrastructure at the local communities, the company said.
In addition to Kok-Jon project in Kazakhstan, EuroChem is developing two potash deposits in Russia, VolgaKaliy and Usolskiy Potash.
